SHADE-ROLLER.

Specification of Letters I atent.

Patented'Oct. 24, 1916.

Application filed June 4, 1914. v Serial N 0. 842,820.

To all whom it may concern Be it known that I, EDMUND F. HAR'rs- HORN, a citizen of the United States, residnewand useful Shade-Roller, of which the following is a specification.

The objects of this invention are: First; to provide, in a roller without a pawl, mechanism to hold the spring in wound-up condition when it is removed from the supporting brackets. Second: to adjust the length of the roller to fit window openings of different widths. Third: to utilize the device without change as a pawl roller. These and further objects will more fully appear from the following specification and accompanying drawings,considered together or separately In the drawingsz'fFigure 1 is a part of a window, showing a shade and roller embodying my invention; Fig. 2 is a view of the roller showing the extensible end, the parts being in section; Fig. 3 is a sectional view of the roller taken onthe line 3, in the direction of the arrow, in Fig. 2; Fig. 4-is a sectional view of the roller taken on the line 4, iniFig. 2,- in' the direction of the arrow; Fig. 5 is a sectional view of the roller, on an enlarged scale, showing'the mechanism for locking the spring in wound-up condition; Fig. 6 is a sectional View, on the line '6, of Fig. 5, looking in the direction of the arrow; Fig. 7 is an end view of the cap of the roller; Fig. 8 is a viewof the" pawl and actuating finger; and Fig. 9 is a view of the cover plate for holding the pawl in place on the spear.

In all of the views, likeparts are designated bythe same reference characters. I My device is particularly adapted for use in car windows. Shadesin such windows are provided'with locking means at the bottom and they require: no pawls to hold the shade in open or expanded condition. The rollers have to be removed at intervals for cleaning purposes and-it is desirable that when so removed the spring will be kept in wound-up condition. Therefore, one of the objectsof the invention, as before stated, is to hold the spring in wound-up condition when the roller is removed from its brackets. The particular mechanism for attaining this feature of the invention will be first described.

:Referring to the drawings, 1 represents the roller, carrying the shade 2 wound thereon. The pin end of the roller engages with a bracket 3. The spear end of the roller engages with the usual notched bracket 4. Both of these brackets are located in the usual manner within the window frame 5.

Within the roller is the usual rod 6, about which is wound the usual spring 7. At the end of the rod is a spear 8. Associated with this spear is a detent ring 9, having an opening making a very loose fit with the spear. Projecting from the inside of the ring is a pawl 10. This detent'is best shown in Fig. 8 and I prefer to make it with an inclined bearing face as shown. This detent is adapted to engage with a notch 11 formed in the spear. Associated with the ring is a finger piece 12.: On the outside of the spear and turning with it is a plate 13. This holds the ring in position and keeps it from dropping off the spear. In the plate 13 is an opening 14 in line with the notch 11. The purpose of this opening is to allow the operator to see the detent 10 when it is in place within the notch 11. On the end of the rod 6.is a cap 21, having an opening 22 forming abearing for the spear. This cap is preferably flanged as shown and secured in place within the end of theroller. One part of the flange is cut away and forms a notch 28. The purpose of this notch is to allow the finger piece 12 to project outward beyond the side of theroller, and also to compel rotation of the detent with the roller. The operation of this feature of the invention is as'follows: When it is desired to remove the roller from the window frame, the shade is raised or lowereduntil the finger piece 12 is in the. up-and-do-Wn position shown in Fig. 6. The operator will then, by raising the finger piece 12 with his finger, engage the pawl 10 with the notch 11. Then by letting the shade unwind very gradually, the detent may be. caused to engage with the notch so that the straight side of the detent engages with one side of the notch, thereby locking the spear against rotation and preventing the unwinding ofthe'spring. The roller may then have the end of the spear lifted out of the notched bracket 4. In placing the roller and shade back in the window frame, the pin end of the roller is introduced into the bracket 3 and then the spear is introduced within the notchin the bracket 4. The shade is now unwound to a small extent which will release the notch 11 from engagement with the detent'lO and the weight of the ring and finger piece will cause it to become disengaged from the notch. In car windows there is usually a hooding in order to conceal the roller and the devices for locking the detent are hidden from view. By my invention, however, the operator may, by the sense of feeling, engage the detent with thenotchand lockthe springin wound-up condition. In thedrawings, the usual hooding is indicated by the character 24. c

The second feature of my invention relates to means for adjusting thelength of the rollers so that they may be used with window openings of different widths. Railway cars, particularly steel cars, are so made that there is a slight difference in widths between various window openings. This to some'extent is caused by the sagging of the frame in building the car. At intervals of time the movable fittings of the cars are taken out for cleaning, and, after being cleaned, the shades are put back. The per sons who do this have great diiiiculty in assorting the shades so that they will fit the proper windows. Any mark which may have been associated with a window to identify the particular shade cannot be relied upon as it will be likely to be obliterated or removed by the varnishers and painters. I I

attain the second object of my invention, by making the roller adjustable as to length so that it will fit any window, and will not have to be replaced in a particular window frame, by the following mechanism: I make the roller out of sheetmetah'as shown, preferably'tin. On'the pin end of the roller is an extension 15. This extension is provided with adeep channel 16. On the end of the roller is adepressed lip 17 This lip has an opening in it through which passes a screw 18. By depressing the lip the head of. the screw will not project beyond the periphery of the roller and therefore will not disarrange'the shade when wound up Associa-ted withthis screw is a block 19. This block is provided with an opening as shown.

Through this opening extends a strip 20.-

The strip may bemade of metal, suchas tin. base of the channel and is secured in position thereby. The other end of the strip is free and unattached as shown'or it may be hooked to the base of the channel in the same manner as is the end.25. By setting the screw sop'that it engages tightly withrthe strip, the 'block is locked in place, and the extensionis 'held immovably upon the roller.

-B'y loosening the screw, the strip may be slid through the block due to the pulling out or pushing iniof the extensionito make the roller longer or shorter.

Oneendishooked at 25 aroundthe The. thirdobje'ct of -the .inventionis to utilize the device as a pawl roller without change. It is apparent that when the spear is put in place in the bracket with the notch roller, thus making the fitting "ofgeneral application. The device, therefore, although particularly adapted for use with spring rollers without pawls, may be, by a simple reversal when introduced within the bracket,

made to act and function as a pawl shade roller.

In accordance with the provisions of the patent statutes, I have described the prin ciple of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that-the apparatus shown is merely illustrative and that the invention can be carried out in other ways.
